JOHN KAISER, OF SENECA FALLS, NElV YORK.

HYDRANT.

SPECIFICATION forming part of Letters Patent No. 401,652, dated April 16, 1889.

Application filed November 1'7, 1888. Serial No. 291,128. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN KAISER, of Seneca Falls, county of Seneca, in the State of New York, a citizen of the United States, have invented certain new and useful Improvements in Hydrants, of which the following is a specification, reference being had to the accompanying drawings, in which Figure 1 is a vertical sectional elevation. Fig. 2 is a like View showing some differences in detail construction. Fig. 3 is an elevation of the tubular valve detached without the packing. Fig. 4 is a vertical section of Fig. 3. Fig. 5 is a transverse section on the line y y in Fig. 1, with the spring-packing. Fig. 6 is a transverse section 011 the line on m, Fig. 1, showing the irregular forms of the pack-nut. Fig. 7 is a vertical sectional view of the upper portion of the hydrant, taken through the elevating-screw.

This invention relates to hydrants adapted to be connected to a water pipe or main,and in which the valve is located below the frostline, and is operated by a valve-rod extending up through the body of the hydrant and actuated vertically by a hand-wheel and screw.

The object of my invention is to improve the method of connection to the water pipe or main, to improve the valve construction, to increase the water-way, to prevent leakage at the top, to perfectly close the drainage-ports when the valve is open, and, in general, to improve the construction and utility of the whole hydrant.

My invention consists in the several novel features of construction and operation hereinafter described, and which are hereinafter specifically set forth in the claims annexed.

It is constructed as follows: A is the tubular shell comprising the body of the hydrant, provided with valve-seat 1, adjacent to the bottom, at the bottom with a branch, 2, for mak ing a horizontal connection, and with a branch, 3, for making a vertical connection, and 4: is a nut or cap adapted to screw onto either branch to close it when the other is to be used. It

will be seen that the months or outer ends of these branch pipes 2 3 are conical or taper in wardly on their interiors, and that the nut or cap 4 has a conical plug, 3, adapted to fit within this conical mouth, and thus make the water-tight j oint, and an interiorly-screwthreaded flange, 4:, adapted to receive the screw-threaded end of the branch pipe. A packing-ring, 2, may, if desired, be placed in the bottom of the groove formed by the conical plug and the said flange, thus making a perfectly-tight joint.

5 5 are the drainage-ports at the bottom of the water-chamber.

6 is the spout, and 7 is a flange around the top of the body, the top being also shouldered at 8, forming an internal rabbet, which may be shallow, as shown in Fig. 1, or deep, as shown in Fig. 2, and at 9 the interior of the pipe is wholly or partially squared.

B is the valve, which is of substantially cylindrical form, closed at the bottom and opened therefrom out through the top, and also provided with the vertical slotways 10 11, opening out through the periphery into the waterchamber above and below the central portion of the valve, and the upper end or neck, B, is threaded either internally or externally to receive the lower end of the tubular valve-rod 12. The central portion of the valve 13 is plain and provided with perforations 14, and 15 are circumferential flanges of proper size to fit the body at that point, and 16 is a packing of any properly-flexible material inserted or secured between the flanges 15, or, as shown in Fig. 5, of spring metal, secured at one end to the valve, and the other end, being loose from its spring elasticity, fits closely against the inner wall of the body, so that whenever with either construction of packing the water is let on by raising the valve the drainageports will first be covered by the packing, and then the water-pressure through the ports 14 will force the packing outward against and completely close the ports.

I cut slotways or perforations through the tubular valve-rod, so as to connect the waterchamber within the valve-rod with the waterchamber outside thereof, and thus increase the water-way of the hydrant by the use of a double chamber merging into one chamber, and only requiring one set of drainage-ports to drain them both.

C is a cap, the base of which is flanged, as at 18, to fit over the flange at the top of the body, and 19 is a Babbitt or other soft-metal packing either cast onto the lower face of the cap and secured by dovetails or otherwise, as shown in Fig. 1, or, as shown in Fig. 2, consisting of a disk of like material, with a disk of like or harder material placed on top of the packing-disk, and the two disks held flrmly together and the packing-disk held rigidly to its seat by the cylindrical flange or collar between the base of the cap 0 and the disk 20, and by which the top of the hydrant s closed, excepting around the valve-elevatlng rod, where it passes through the packing. The top of this cap may be either bell-shaped, as shown in Fig. 2, or may consist of merelya spider-frame, as shown in Fig. 1, at the top of which isanut to receive the screw 22, which is tubular.

23 is the elevating-rod to open the valve, provided with a shoulder, 24, against which the screw abuts, and the tenon 24, on which the tubular screw is sleeved, and 25 isa handwheel mounted upon the upper end of the screw-cylinder, and the screw is held in position and the wheel secured in place by the nut 26 upon the top of the tenon 24. (See Fig. 7.) The purpose of this arrangement, it will be understood, is to allow the screw to turn in its bearing and elevate the valve without turning the latter or the pack-nut 27, now to be described. The lower end of the rod 23 is secured to or integral with the packing-nut 27, into the lower end of which the valve rod is screwed or otherwise secured, thus closing the top of this rod, and this packing-nut has one or more of its sides squared off, as shown in Fig. 6, so that it can only be inserted one way into the top of the hydrant, the interior surface of which at that point is of the same shape as the packingnut, and this interior surface guides the packing-nut in its vertical movement, and when the valve is open the top of the packing-nut screws tightly against the packing 19 and makes a tight joint therewith, so that what little Water is forced through the joint between the packing-nut and the body cannot escape upward around the elevating-rod, but will be forced downward into the waterrchamber.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a hydrant, the combination, with the tubular body having the drainage-ports 5 and a valve-seat and the hollow valve in said body having the circumferential flanges 15, completely filling said body, and perforations between said flanges, of aloose packing-band having its ends overlappinglocated between said flanges over said perforations, as set forth.

2. In a hydrant, the combination, with the tubular body having the drainage-ports 5 and a valve-seat and the hollow valve B, having the circumferential flanges 15, and perforations between. said flanges, of a loose packingband located between said flanges and secured at one end' to said valve, as set forth.

3. In a hydrant, the combination, with the tubular body having the drainage-ports 5 and the valve-seat and the hollow valve B, having circumferential flanges 15, and perforations between said flanges, of aloose packing-band located between said flanges and coiled around said valve more than once, as set forth.

4. In a hydrant, the combination, with the tubular body having a valve-seat and the drainage-ports 5, and the hollow valve B, having the circumferential flanges 15, and perfo= rations between said flanges, of a loose packing-band completely filling the space between said flanges and coiled around said valve more than once and having one end secured thereto, as set forth.

In witness whereof I have hereunto set my hand this 12th day of November, 1888.

JOHN KAISER.
